<p><P>PROBLEM TO BE SOLVED: To provide a circuit structure body which can securely detect the soldering defect of an electronic component connected to a bus bar and a control circuit board and is superior in connection reliability. <P>SOLUTION: An opening 14B is formed in the circuit board 11, and a connection protrusion 16 projected into the opening 14B is formed in the bus bar 13. The connection protrusion 16 is soldered with the source terminal 17B of the semiconductor switching element 12A. Thus, a soldering state is more easily recognized by eyes compared to a case when the bus bar 13 and the source terminal 17B are soldered at the base of the opening 14B. Consequently, connection reliability of the semiconductor switching element 12A can be improved. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
